+        ---help---
+        This option allows you to specify the maximum number of scatter-
+        gather entries per I/O. The driver default is 128, which matches
+        MAX_PHYS_SEGMENTS in most kernels.  However in SuSE kernels this
+        can be 256. However, it may decreased down to 16.  Decreasing this
+        parameter will reduce memory requirements on a per controller instance.
